BorgWarner wins $4 million prize to design American-made EV fast charger
The Department of Energy prize will support the development of a cost-effective direct current electric vehicle fast charger made of US-sourced components.
You know solar has made it when fossils fund misinformation campaigns
As solar has grown, the fossil fuel industry has begun to attack it by funding misinformation campaigns online and among Facebook groups.
Storing renewables in depleted oil and gas wells
US researchers have proposed the use of hydraulically fractured oil and gas wells to store renewable energy via compressed natural gas, with the levelized cost of storage potentially coming in at $70/MWh and $270/MWh. They said wells could also be used to store other renewable gases such as carbon dioxide or hydrogen in the future.
Repurposing EV batteries for off-grid use gains support in British Columbia
Moment Energy is one of several companies and projects supported by the ARC program, which aims to provide clean-energy storage to urban and remote diesel-dependent communities in British Columbia.

Could ‘hot carrier’ solar cells break the theoretical efficiency limit?
Up to 50% of the energy absorbed by a solar cell is lost as heat. Scientists are now developing a third generation of “hot carrier” solar cells that take advantage of this heat, potentially breaking the Shockley-Queisser limit of silicon-based PV.
Photovoltaic cell harvests energy day and night
Stanford researchers develop a device that harvests energy from the temperature difference between the PV cell and the air.
